I just got 50 photos approved (03/16/2011) and think about being exclusive, considering the most recent upload limit change.
I have been starting to shot and upload photos since the end of this Jan., after getting my first DSR as a Christmas gift for myself. I have been working on it for less than two months as a hobby which gives me a lot of fun and things to do after working. So far the sales are quite slow, and I've only got 5 sales with one tiff sale (11 credits), but I don't feel so bad. With the new upload limits, I think I'll focus more on quality, instead of quantity, which should not be too bad for me, I think, since I don't have a lot of time to shot, process and upload. From that, I think I probably will go exclusive which hopefully will give me more advantage in terms of searching or other things I might not know.
Anyway, here is my 50th photo approved, and let's sail and get more sales, and more fun, no matter how high the wave is:
